Air India has grounded a Boeing 787-8 Dreamliner jet after one of its pilots reported a possible defect in the aircraft's fuel control switch.

The airline said in a statement on Monday that it had informed India's aviation regulator about the issue and that it was getting the pilot's concerns checked on a "priority basis".

"We are in contact with Air India and are supporting their review of this matter," a Boeing spokesperson said in response to an email.

The grounding comes amid an ongoing investigation into a plane crash last June involving an Air India aircraft of the same model which killed 260 people.

The airline did not specify the nature of the issue flagged by its pilot or details of the flight.
